Independent Expert In Audio Analytics?

An organization has asked us for a recommendation on an independent expert who specialized in audio analytics. This is not camera connected but purely audio side. For example, monitoring audio for aggression or yelling, etc.

They are not looking for manufacturers here. They want someone who is independent to give them feedback / advice / consulting on what works / what doesn't, what's possible etc.

If you are one or know of one, let me know.
